The Donjoy Armor Knee Brace with Fourcepoint is the ultimate knee brace for the protection of the ACL and hyperextension injuries. The Donjoy Armor with Fourcepoint Knee Brace is a hinged knee brace using the Donjoy Fourcepoint Hinge Technology. The spring loaded Fourcepoint Hinges of this Donjoy Armor knee brace keep the hamstring in constant tension. As the hamstring is attached to the tibia (or shin bone) this tension pulls the tibia back keeping it stable and almost entirely eliminating the chance of an ACL injury.
